Poulose" Hi, Here is the series which adds support for the CCI-500 PMU. Could you please apply this for 4.2 ? Please let me know if you need a pull request, I could ask Will to setup one. --- This series adds the support for CCI-500 PMU, by reusing and rearranging the CCI-400 PMU driver code. CCI-500 (the new Cache Coherent Interconnect IP) has a PMU with 8 independent event counters and supports profiling events related to master/slave interfaces along with the global events(cci internal events). The series also adds aliases for events for all the supported CCI PMUs(CCI_400{r0,r1}, CCI_500). Patches 1/7 is a fix posted by Mark Salter, which has been posted to arm@kernel.org already. I have included it in this series, as this series applies on top of it. Patches 2-5 - Creates an abstraction of a CCI PMU and makes the CCI-400 driver code to make use of the abstraction. Patch 6 - Adds the CCI-500 PMU driver support Patch 7 - Adds the aliases for CCI PMU events (specific to chipsets). With the series, one can use named events for the CCI pmus. e.g, CCI-400 # perf list | grep CCI CCI_400/cycles/ [Kernel PMU event] CCI_400/mi_retry_speculative_fetch,source=?/ [Kernel PMU event] e.g, CCI-500 # perf list |grep CCI CCI_500/cci_rq_stall_address_hazard/ [Kernel PMU event] CCI_500/cci_snoop_access_filter_bank_0_1/ [Kernel PMU event] Testing was performed on a fast model, with perf fuzzer and functional tests for the CCI-500 PMU. --- Changes since V1: https://lkml.org/lkml/2015/5/5/323 The series remains functionaly pretty much the same, except for a minor fix in the Kconfig default for CCI-500. - Pulled in a CCI-400 config fix posted separately, as Patch 1/7. https://patchwork.kernel.org/patch/6387121/ - Add the similar Kconfig changes for CCI-500 as fixed in the patch above. - Dropped Mark Salter's fix for CCI, which is now queued.
